Weather radar not accurate, too vague

I really wanted to like Windy. I downloaded the app, created an account, everything. The map just wasn't accurate. There I was, staring out my window at a downpour. Wunderground showed yellow radar of the rain right over my street, Windy just displayed a light blue haze, 8 mins old, and not over my street yet. I kept refreshing hoping it would catch up, but too late, the weather had already moved on.
